After having successfully gone from Verizon to T-Mobile on my iPad mini, I thought I'd get a micro SIM and go for the free 200 MB on my iPad 3. After I shut it down, put the new SIM in, and then re-provisioned, all seemed to go well (I see T-Mobile up in the upper-left-hand corner). What I'm not seeing under cellular data is the "View Account" button. Instead, I have the "Set Up Personal Hotspot" button, which clearly isn't what I want. I've tried resetting all network settings, but that didn't seem to work, either. So...what have I done wrong? I'm feeling pretty stupid right now. Thanks!
